The x axis is timestamps. The y axis is an integer. Haven't found exactly why this behavior occurs or when. It should be connecting dots left to right, not top to bottom!!
Hi @Ori, this behavior can happen when the input data is ordered/sorted in a different order than the date. Choosing the date as the x-axis doesn't automatically order the line.
If the data is coming from a SQL query you could ORDER BY date_column_name ASC, or if you want to use javascript you can sort by the date like so: return data.sort((a,b) => new Date(b.date) - new Date(a.date))
